WINDOW SUPPORT AND LOCK.

SPECIFICATION forming part of Letters Patent N0. 783,119, dated February21, 1905,

Application filed May 9, 1904. Serial No. 207,180.

To all whom it may concern:

Be it known that I, ERNEST A. HORNBOSTEL, J r., a citizen of the UnitedStates, residing at Des Moines, in the county of Folk and State of Iowa,have invented a new and useful indow Support and Look, of whichthefollowing is a specification.

My object is to provide a simple, strong, and durable device that can bereadily applied to a window-sash, by means of two screws to support thewindow at any elevation desired and also to lock it securely when in aclosed position.

My invention consists in the construction, combination, application, andoperation of three parts, as hereinafter set forth, pointed out in myclaims, and illustrated in the accompaying drawings, in which Figure 1is a side view of a metal clamp adapted to engage a window-casing. Fig.2 shows a link adapted for pivotally connecting the clamp with a plateadapted to be fixed to a window-sash. Fig. 3 shows the flat plate. Fig.a shows the three parts pivotally connected. Fig. 5 is a modification ofFig. 1 and shows a rubber covering or cushion on the clamp. Fig. 6 is aface view of parts of two sliding windows in a window-frame and shows myinvention applied to the sashes as required for practical use.

The letter a designates a fiat metal plate, about two and a half incheslong and a half inch wide, bent at right angles at its ends to producelateral projections b. It is obvious it may vary in size and weight. Atits center and at one edge it has an integral rightangled projection 0,provided with an aperture (Z for pivotally connecting a link therewith.

A link f, made of flat metal by means of a die, is about an inch andone-eighth long, preferably wider at one end than the other, andprovided with rivet-holes in its ends.

A flat plate 9, that may vary in length and width, is provided withthreerivet-holes.

To pivotally connect the three parts,one end of the link is secured tothe projection d of the clamp a and the other end to the plate g bymeans of rivets h, as shown in Fig. 4.

When the device is applied to a sash by fixing the plate 9 against theface of the side part of the sash by means of screws in such a mannerthat the link f and clamp 60 can be adjusted to incline the link upward,as shown on the lower sash, it will lock the window as required toprevent it from being moved upward and to lock it when in aclosedposition, but will not prevent the window from being pulled down whenthe window is in an elevated position. By turning the clamp a and linkfupward their positions can be reversed, so that the link will inclinedownward, as shown, on the upper sash and as required to lock the sash,so it cannot be moved downward.

It is obvious the lower sash may be retained in an elevated position andthe upper sash in a lowered position for purposes of ventilation and thelower sash locked so it cannot be raised higher to admit a burglar andthe upper sash locked so it cannot be lowered farther for a person togain access.

Having thus set forth the construction, application, and operation of myinvention, its practical utility will be obvious, and what I claim asnew, and desire to secure by Letters Patent, is

1. A clamp for a window-lock, consisting of a plate having aright-angled extension at one of its edges and center provided with anaperture for pivoting a link thereto as shown and described for thepurposes stated.

2. A clamp for a window-lock consisting of a flat plate bent at rightangles at its end portions and having a right-angled extension at thecenter of one of its edges provided with a rivet-hole and a link pivotedto said extension and means for pivotally connecting the link with awindow-sash for the purposes stated. 1

3. A window support and lock comprising a clamp consisting of a flatplate bent laterend of the link to operate in the manner set ally at itsGfilds and having a right-aggled proforth for the purposes stated.

jection at t e center of one of its e ges provided with a rivet-hole, alink pivotally con- ERNEbT HORNBObTEL nected With said right-angledprojection and Witnesses:

a flat plate adapted to be fixed to the face of L. L. LEIBROOK,

a Window-sash pivotally connected with the I THOMAS Gr. ORWIG.
